It's suppose to be one per phone, doesn't matter how many phones I'd contact Sprint about that although it might be too late. I got 3 phones about a year ago and got 2 rebates, although I had to switch a number off a phone and one of the rebates screwed up but I would have gotten three. To be honest from that day I'll never use a rebate ever again it's much easier to just get a phone from a 3rd party and let them handle it.
